There are many security issues involved with e-commerce. Following is a brief list of potential hurdles or issues: 1. Back Doors and Trojan Horses
2. Viruses and Worms
4. Active Contents, Active X
5. Eavesdropping & Password Attacks
6. IP Address Spoofing
7. DOS – Denial Of Service attack

Trojan Horses apparently look harmless, however, they can be doing something dangerously wrong in the background. ‘Happy99.exe’ is a Trojan Horse that after displaying firework, sends its copies to email addresses found on the system. 2.
